A heat pipe type automatic flue-curing machine

Abstract

The invention provides a heat pipe type automatic flue-cured tobacco machine, which includes a thermal insulation box and a thermal insulation partition. The interior of the thermal insulation box is divided into upper and lower sections by a partition, the upper section is a heating section, and the lower section is a dehumidification section. The heat pipe type regenerator is divided into upper and lower ends by the insulation partition. The upper end is the heat release end, which is in the heating section of the insulation box, and the lower end is the heat absorption end, which is located in the dehumidification section of the insulation box. The heating section It consists of heat pipe regenerators, compressors and condensers connected in sequence. The dehumidification section is composed of air inlet flanges, fans, heat pipe regenerators and dehumidification evaporators connected in sequence. The invention uses electric energy, There is no coal-burning pollution; it makes full use of the condensation heat of hot and humid air and the heat of outside air during the dehumidification process of the barn, and adopts heat pipe recovery technology to further improve the heat recovery efficiency of hot and humid air, reduce the electric power of the dehumidification system, and save electric energy. And the dehumidification process of the flue-cured tobacco room is canceled, which further improves the quality of the flue-cured tobacco.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco, in particular to a device capable of automatically roasting tobacco leaves according to a set program and recycling heat. Background technique [0002] At present, the main equipment for tobacco roasting in my country is standard intensive roasting house, which uses coal as energy. Tobacco curing has a strict temperature and humidity time curve. The means of controlling the temperature of the barn is to control the firepower of the coal-fired furnace, and the means of controlling the humidity is to dehumidify through the dehumidification window of the barn. During the curing process of tobacco leaves, it is necessary to dehumidify in a timely manner. The moisture exhaust airflow not only has high relative humidity, but also its temperature (40°C~60°C) is higher than the ambient air temperature, carrying a large amount of low-temperature waste heat. Therefore, at present, there are t...

AI Technical Summary

Problems solved by technology

Heat loss not only increases excess coal consumption, but also emits more harmful gases and pollutes the environment

[0004] 2. Manual intervention operation, the quality of flue-cured tobacco varies from person to person, and it is difficult to control

The coal-fired firepower of the dense baking room needs to be controlled manually. During the baking process, someone must be on duty, and the labor cost is high.

[0005] 3. The aroma of flue-cured tobacco is lost, and the quality is difficult to improve

The dense barn relies on exhaust to control the humidity. During the dehumidification process, the precious aroma of the tobacco leaves is also released, which affects the quality of the tobacco leaves.
